I sign in and click on a game and when it comes up I have to sign in again, it might go good fort hat part of the game but when you move on to the next part of the game you have to sign in again, getting tired of it

I spend numerous hours playing Publishers Clearing House online contest games. I have situations,where I'm at the end of a PCH app online game and the game gives me an error message about my server, or after spending over an hour to complete the game it stalls and freezes. Then I go back into the app and start over and it freezes again. It us very, very frustrating, because many if the PCH games take forever to complete. Also, I receive numerous emails from PCH that are marketing type emails where I have to scroll down long lists of merchandise to view before being able to submit an entry in the sweepstakes. Annoying.
